Patent DE-3623539-A1 (DE)
Title: Rotary switch
Inventor: LAUBLE ERHARD
IPC: H01H19/58
Filed: 1986-07-12
Abstract: A rotary switch (2) (Figure 3) is used, for example, for voltage changeover switching or as an on/off switch in the case of small electrical apparatuses, for example a razor. This rotary switch (2) has a rotating knob (5) which is inserted into a housing passage (4) in an apparatus housing (3) and has an outer grip part (6) as well as, adjacent thereto, a collar (8) with a somewhat larger external diameter. Contact springs (10) are located on the inner end of the rotating knob (5). A contact-pressure spring (9), which is in the form of a plate, is inserted between the collar (8) of the rotating knob (5) and an opposing-bearing plate (abutment plate) (7) which is provided in the housing passage. This contact-pressure spring (9) on the one hand assists the contact pressure by the prestressing of its spring and on the other hand has bead-like latching studs (18) which engage in mating recesses (19) in the attachment (8). The contact-pressure spring (9) is thus used simultaneously for assisting the contact pressure and as a latching spring for different switch positions. <IMAGE>

Title: Radio receiver with rod antenna
Inventor: WIETZKE JOACHIM DIPL ING
IPC: G04G21/04
Filed: 1987-01-20
Abstract: By using an electrical antenna in a radio clock receiver, direction-independent all-round reception without reception minima can be achieved, even in the long wave range. The electrical antenna confounds the current belief that only ferrite antennas can be used for radio clocks and is superior to these antenna if the circuits which are connected immediately to the antenna are suitably selected and dimensioned.

Title: Device for washing tubers underwater
Inventor: SCHNEIDER ALFRED
IPC: A23N12/02
Filed: 1987-05-22
Abstract: A device for washing tubers underwater having a rotating screening drum (1) which is open on both sides and through which the tubers pass is to be simplified. To achieve this, the screening drum (1) is arranged with an axis of rotation which is inclined in such a way, and/or the screening drum (1) is conical in shape such that its outside is most deeply immersed in the water at the charging end and projects from the water with its entire circumference at the discharging end. The tubers are therefore conveyed out of the water by the screening drum itself. A spraying device (24) is used for final cleaning of the tubers with fresh water shortly before they leave the drum. <IMAGE>

Title: Impression tonometer (impression comparator)
Inventor: OBAL ADALBERT DR MED
IPC: A61B3/16
Filed: 1987-06-04
Abstract: Device for measurement of the intraocular pressure by the impression tonometer principle, it being possible to use this device simultaneously for determining the changes in the wall tension of the eyeball (impression comparator). The object is to improve the position-dependent impression tonometer according to Schlötz, and it is achieved in that the gravity-dependent pressure of the piston and the foot plate is replaced by a gravity-independent spring mechanism. The measurement process and reading of the values found are separated. It can be applied for measuring the intraocular pressure in the middle of the cornea and for determining the eyeball tension on other accessible parts of the eyeball.

Patent DE-3725629-A1 (DE)
Inventor: LAIG-HOERSTEBROCK HELMUT DIPL
IPC: H01M4/62
Filed: 1987-08-03
Abstract: Alkaline MnO2/Zn cells having nickel-plated steel cups as the cathode collector show deterioration of their discharge characteristics after high-temperature storage, which can be prevented by an additive in the cathode paste which forms a strong complex with nickel. Nickel oxide layers of high ohmic resistance, which are the cause of the contact resistance between the cathode and the nickel coating of the steel cup, are accordingly dissolved or transformed. Imidazole, 2-picolinic acid, dimenthylglyoxime, 4,5-dihydroxbenzene-1,3-disulfonic acid and 1,10-phenanthroline are particularly effective additives for compounding into the cathode. Preferred amounts are between 0.001 wt. % and 1 wt. %.
Patent DE-3731351-A1 (DE)
Title: Process for preserving foods
Inventor: WIXFORTH BRUNO
IPC: A23C3/08
Filed: 1987-09-18
Abstract: The invention describes a process for microbiologically stabilising or preserving water-containing foods by plant parts of Juglans genera. This is achieved by adding dried finely ground plant parts in amounts of 0.05 to 0.5%, based on the water content of the food, or an extract of these plant parts. Aroma substances, aroma stabilisers and/or flavour enhancers can be added to the extract. Because of the instability of the active constituents of the Juglans genera, the microbicidal action lasts for one to seven days before the active substances are metabolised or degraded to form microbiologically inactive compounds. This process is highly desirable in the production of some foods and in some sectors of the food industry and is sufficient to protect these foods against microbiological decay during the processing and packaging phase, at risk from infection, up to the hermetic seal in finished packages, although in the final product, after the expiry of a certain time of action, preservative is no longer active or detectable.

Title: Double-piston internal combustion engine with a central control groove or separate rinsing and charging
Inventor: EICKMANN KARL
IPC: F01B11/00
Filed: 1987-11-03
Abstract: In a double-piston unit in which a piston of low mass carries out a reciprocal movement in cylinders with the same axis, the preferably hollow piston rod which connects the pistons, which are preferably thin, obliquely positioned plates of low mass, is provided with a single control groove which successively controls the flow of fluid out of an inlet in the centre housing between the cylinders in such a way that the inlet fluid at one time flows into one of the cylinders and at a following time into the other of the cylinders. The plurality of control grooves from published patent applications of the inventor are thus reduced to a single control groove, the flow cross-sections are constructed in a more streamlined fashion, the unit is simplified, its manufacture made cheaper and at the same time the degree of efficiency and the power with a given weight of the unit, which can be used in particular as a high-power internal combustion engine, are increased. In order to increase the power per given weight and dimensions and in order to increase the efficiency and the environmental friendliness by better combustion and less poisonous exhaust gases, in the advantageous embodiment the rinsing of the cylinder spaces is separated in terms of timing and spatially from the charging of the cylinder spaces so that in this embodiment the engine achieves, or approaches, the degree of cleanliness of operation of a four-stroke engine. <IMAGE>
